What can you do with the over fermented dosa batter?

Fermentation is quite a tricky process in making dosa and if you don’t do this process properly, you won’t be able to make the perfect dosa.

Some of the tips to deal with the over fermented dosa batter are given below;

Drainage of excess water before mixing the batter:

When your battery is over fermented,  it used to have a thin layer of water over it.

This water is useless and if it is mixed with the batter, it will make your batter sour as this water is produced as fermentation.

So, it’s very important to get rid of this useless water.

And once you mix such water with the batter,  the removal of the sour taste from the batter will become difficult.

So, drain this excess water as you can add some warm water to it later to make perfect dosa.

Adding sugar to the batter:

Fermentation makes the taste of the batter sour which is unpleasant.

So to get rid of this sour taste, you can add a pinch of sugar to it. It will balance the taste.

Sugar also helps you in getting a crispy, brown coloured layer to your batter.

Addition of rice flour to the batter:

The addition of rice flour to the batter will also help you in fixing the problem of the sour taste of the batter as a result of over fermentation.
